Vehicle prying type oily sludge intelligent module processing system

Abstract

The invention discloses a movable processing method and a device. The movable processing method and device are aimed at dispersity and complexity generated by oily sludge, and drug toxicity caused by refining process, and conduct innocent treatment upon self heating value of the oily sludge. A combination processing method of thermo-chemistry refining and pyrolysis burning is adopted to conduct intelligent combination aimed at geographical features and mechanism of production of the oily sludge. A total craft process includes: oily sludge earlier stage processing -> pyrolysis burning -> desorption -> filtering -> cyclic utilization -> discharging, wherein each module not only has an independent function, but also has a combination function, and can achieve functions such as pyrolysis burning, decomposition absorption, crude oil recovery, sludge elutriation, sludge drying and sludge solidification. The oily sludge after processed does not contain petroleum and other injurious ingredient and accords to environment-friendly discharging requirement, and the system can continuously operate for 24 hours, conducts crude oil recovery for sludge with high oil, and achieves the aims of reduction, harmlessness and reclamation of treatment and disposal of hazardous wastes.

Description

technical field [0001] The present invention is a movable treatment method and device for harmless treatment by relying on the calorific value of the oily sludge itself, aiming at the dispersibility and complexity of the oily sludge and the toxicity of the agent caused in the refining process. Background technique [0002] Oily sludge is the sludge and sand precipitation carried in the crude oil in the process of oil extraction and refining, the scum and bottom mud of the oil extraction sewage, and the pollutants formed by the mixing of the ground crude oil and the soil and debris generated in the drilling and oil extraction process. . Oily sludge is an inevitable product in the production process of oilfields and cannot be eradicated within a certain period of time. Among them, the barrier properties of oil and the toxicity of minerals will inevitably cause pollution to the environment. It is listed as a hazardous waste in the "National Hazardous Waste List" and contains mo...

Problems solved by technology

Separation method: oily sludge→dilution and sedimentation→heating and tempering→separation, a part of crude oil is recovered, but it needs to be added into chemicals and increase energy consumption, the treatment is not thorough, and the separated mud and sand still contain certain petroleum substances, which cannot reach To meet the requirements of environmental protection, further treatment is still required; solidification method: oily sludge → adding additives → press filtration → stacking in garbage dumps, additives are needed, and costs are increased. The oil content in the dry sludge is high and wastes a lot, and it requires a large area after solidification Ar
